2 Claims.

-Our invention relates to dispensing device particularly adaptable and designed for dispensing tooth powder.

The main object is to provide a highly efficient, 5 inexpensive and easily operated device to be mounted in any accessible place, as in a bath room, and further to provide means for releasing variable quantities of powder directly on the bristles of a tooth brush without contact of the hand or fingers, said means of extremely simple construction and involving only two moving parts. Other objects, advantages of use and the preferred construction are hereinafter fully set forth, reference being had to the accompanying drawing, in 15 which- Fig. l is a top view of our dispensing device attached to a wall the receptacle lid being omitted.

Fig. 2 is a front view of the device. Fig. 3 is a partly sectional right side elevation 20 of Fig. 2 and showing in section as on line 3-3 in Fig. 2 the parts of the device forward of its wall plate.

Fig. 4 is a bottom view of Fig. 3 showing the powder release slide in open or releasing position. 2 Referring to the drawing by reference numerals, like characters designating corresponding parts in the various views, the preferred embodiment of our device includes first a wall plate 5 with a number of countersunk holes 6 by means 30 of which the plate may be secured as with screws 1 onto a wall 8 or other vertical surface.

9 is an upright, preferably cylindrical powder receptacle, retained in parallel spaced relation to the plate 5 by means of a connecting main horizontal web II] at or near the lower end of the receptacle. II is an upper two-part web parallel to web- III both parts in horizontal plane and extending from the opposite sides of the receptacle to the wall plate, the outer edge parts provided with notches IIN.

Said notched parts are of such shape as to permit hanging of a tooth. brush in each as is well known in the art.

9C designates any suitable type of cap for the receptacle 9 and which may be readily removed 45 for the purpose of pouring a quantity of tooth powder into the receptacle (see Fig. 3). The lower end of the cylinder is tapered as 9T to a central outlet I3 which delivers powder directly into a reciprocable powder receiveing and delivering valve which will now be described.

The powder measuring and delivering means includes an elongated, fixed, horizontal tube I4 preferably quadrangular in cross section and is integral of the lower end part 9T of the receptacle 55 and extends in a plane at right angles to but in spaced relation to the wall plate 5 toward which it is open 'but is closed at its front end, as at MC. The outlet I3 opens downwardly into the bore of the tube I 4 (see Fig. 3). Within said bore is a snugly fitting valve plate I5 reciprocable in the 5 bore and movable by means of a downwardly projecting tongue or extension I5T extending downwardly from the open rear end of the tube. Between the rear face of said tongue and the plate 5 is interposed a helical coil spring I6 under 10 compression.

I5A is a row of apertures in the plate I5 which communicate and register with outlet I3 of the receptacle as the plate is reciprocated in the bore of the tube. It will be readily understood that the apertures I5A are filled with powder I2 when plate I5 is moved forward as from the dotted to the full line positions in Fig. 3. When the valve plate I5 is in rearmost position, as shown in full lines in Fig. 4 and dotted in Fig. 3, the blank front part of the plate is under aperture I3 preventing discharge of powder through said aperture.

However, as the valve plate is moved rearwardly toward the wall plate the apertures I5A are exposed successively at the rear open end of the tube I4 and the powder in them drops out direct- 1y onto the bristles I'IB of the tooth brush IT. The latter is merely held horizontal with its brush end against the valve tongue I5T, bristles up, then pushed toward the wall plate to release the powder in desired quantity the powder dropping, as stated, directly on the bristles I'IB. In Fig. 4 the valve is shown pushed back about the maximum exposing all the apertures I5A and releasing an elongated stream of powder which will drop on practically the entire length of the bristle part of a brush. Releasing rearward pressure, or withdrawing the brush, the valve moves back to refilling position and the operator removes the charged brush for use in brushing and cleaning 40 teeth,

Obviously this device is of highest efiiciency when an easy-pouring powder is used and the device may be used for other than tooth powders, for example, cleansers of which a relatively small amount is required as on a damp or wet cloth, wash cloth or on a brush, or may be used for powder lotions for the hands.

The preferred embodiment of the device, the simple construction and the use of the device have been simultaneously disclosed in the fore- 0 going specification. It is obvious that modifications of structure may be embodied, within the scope of the description and claims, without departing from the scope and spirit of the invention.

We claim:

1. A powder dispensing device of the class described comprising a wall plate, an upright powder receptacle rigidly fixed in spaced parallel relation to said plate, said receptacle adapted to be opened at its top end, its bottom end tapered downwardly and provided with a central outlet, valve means communicating with said outlet and including a horizontal tube integral of the bottom of the receptacle and a slide valve reciprocable in said tube, said valve movable from the communicative position to selective discharge position to release powder downwardly and in spaced relation to the receptacle outlet, said valve comprising a slide reciprocable in the bore of said tube, a downwardly directed tongue integral of said valve member, a compression coil spring interposed between said tongue and the wall plate, said valve formed with a row of vertical apertures passing under the receptacle outlet to be filled with powder, said tube open rearwardoutlet, a downwardly directed arm comprising an integral part of the slide and accessible for contact to move the slide valve into selective position to expose said apertures successively and discharge the contents thereof.
